SEAL STRUCTURE OF A FUEL CELL |
摘要 |
A seal structure of a fuel cell includes a first seal surface formed in a first separator disposed on one side of an electrolyte membrane and a second seal surface formed in a second separator disposed on the other side of the electrolyte membrane, and a sealant collecting structure formed in or outside at least one of the first and second seal surfaces. The sealant collecting structure is constructed of a stepped receding surface formed in at least one of the first and second seal surfaces, a concave or groove formed in an inner portion and/or an outer portion of at least one of the first and second seal surfaces, a space formed outside at least one of the separators, or a stepped recess formed in at least one of the separators. The sealant collecting structure receives an extra sealant therein to ensure uniform sea l pressure acting on the sealant and to prevent the extra sealant from being bulged out to gas passages and to a gas manifold. |
